Summary: this phase i trial studies the side effects and best dose of stereotactic body radiation therapy (sbrt) in treating participants with head and neck cancer that has spread from where it started to nearby tissue or lymph nodes and is at high risk for continuing to spread because the participant cannot undergo standard chemotherapy. stereotactic body radiation therapy is a specialized radiation therapy that delivers radiation directly to the tumor in smaller doses over several days, which may kill more tumor cells and cause less damage to normal tissue.

primary objectives: i. to explore the maximum tolerated dose of head and neck stereotactic body radiation therapy (sbrt) in a high risk participant population ineligible for standard chemoradiotherapy. secondary objectives: i. assess profiles of sbrt toxicity and examine participant (including co-morbidities), tumor and treatment related factors that are associated with sbrt related toxicity. ii. identify any dose volume parameters that are associated with sbrt related toxicity. iii. explore potential dose response relationships between higher sbrt dosing and radiographic response. iv. assess impact of sbrt on participants' quality of life. outline: this is a dose-escalation study. participants undergo sbrt in 5 fractions at least 40 hours apart over 10-18 days. after completion of study treatment, participants are followed up at 0.5, 3, 6, 9, and 12 months.

Eligibility criteria:
inclusion criteria: * the participant must have squamous cell carcinoma proven by histologic diagnosis; for cancers of the oropharynx, p16 staining by immunohistochemistry must be negative; for cancers of the larynx, hypopharynx, oral cavity, nasopharynx, paranasal sinuses, p16 staining is not required * the participant must have clinical stage t1-4, n0-3, m0-1, stage ii-ivc carcinoma as per the 7th edition of the american joint committee on cancer (ajcc) staging manual; participants with t1n0m0 will be ineligible; participants with metastatic disease with a limited metastatic burden are eligible if obtaining local control is determined by their treating oncologist to be an important therapeutic goal * the participant must have imaging documenting a primary tumor, or involved lymph node, ≥ 2.5 cm in greatest dimension * pet/ct is required for all participants, unless contraindicated; this may be acquired prior to study entry or after enrollment prior to sbrt planning * the participant must have a history and physical documented within four weeks of registration and be deemed by a medical oncologist to be ineligible for standard continuous course chemoradiotherapy with cisplatin * karnofsky performance status (ps) ≥ 40 * female participants cannot be of childbearing age, or if they are, must have a negative pregnancy test prior to enrollment and be willing to use contraceptives during treatment and continue for 6 additional months * participants must have the ability to understand and the willingness to sign a written informed consent document exclusion criteria: * participants with t1n0m0 stage i disease * participants who are receiving any other investigational agents * participants with non-squamous cell histology * participants with life expectancy \< 6 months * participants who cannot lie flat for 20 minutes * participants with prior history of head and neck radiotherapy (\> 40 gy) with significant areas of anticipated overlap
